Abstract

Provided is a powder (A) for a magnetic core for producing a powder magnetic core, the powder (A) for a magnetic core including: as a main component a granulated powder (1) obtained by granulating iron-based amorphous powder having been subjected to insulation treatment and having a particle size distribution falling within a range of from 1 μm to 200 μm; and glass powder having a softening point lower than a temperature of the annealing treatment. The granulated powder (1) is obtained by binding particles (2) of magnetic powder each formed of a particle (3) of the iron-based amorphous powder and an insulating coating (4) configured to coat the surface of the particle (3) to each other through use of a PVA aqueous solution having a viscosity of from 3 mPa·s to 25 mPa·s.
